The Tayto crisp sandwich shop has proven to be fairly popular with the sandwich buying public, which means that it's going to be open for a little bit longer. 

The shop sells a number of crisp sandwich variations, including The Cheese and Onion Classic, The Salt and Vinegar Sarnie, The Smokey Bacon Butty and The Prawn Cocktail Treat. 

It sounds simple enough, but the success of the venture has seen Tayto decide to push for a few more days, and the shop will now remain open until St. Patrick's Day, when it was originally due to close on March 15th.
